Removing Relative URLs in JavaScript

Question

I am creating a JS library that has a requirement to look at the form [action] and [href] values ​​and resolve them to absolute URLs.

For example, I am on http: // a / b / c / d; p? Q and meet the href value for "../g" (suppose there is no <base> element). The resulting absolute will be: http: // a / b / g .

Is there a JS library that already does this? I had to believe it.

For more information on what you need, spec: http://tools.ietf.org/html/rfc3986#section-5.4
